Tb all 'whom t may concern A subject of the Kingof Belgium, resid-ing at Scrantomin the county of ,Lackawaniia andy State of Pennsylvania,v have invented a ceri j `tain newfand A useful Improvement in Automatic Musical Instruments,l V of whi'ch the following is a specification.

- The invention relates'4 to the music-sheet nients of the violin class-in which abowing device is provided for each violin string and in which .it is sometimes necessary for one oi' more of'such bowing devices to be held in contact with its string for continuous periods of lconsiderable lengt-h. By the usual methods .of'preparing such sheets this necessity requires very longl slits. in the musicsheet .tending to weaken thev latter and reird'er it unmanageable in the 'feeding mechanisml 'The objectof'this inventionis toA overcome this difficulty and permit the bow ,ing devices or othermusic-producing niechanisms to be held continuously in operative positiiis lfor indeiinitely long periods without weakeningthe sheet.`

The invention consists in cert-ain novel features of"construction and arrangement by which the above object is attained, tobe hereinafter described.

The accompanying drawings'form apart of this specification and show' the manner in which the invention. has been carried out in practice.

Figure l is a face'.view of a portion of4 a music-sheet or rol'lkperforated in accordance with the invention, and Fig. 2 is a longitudinall vertical section, partly in elevation, showing a portion of a tracker-board and its connected tubes, constructed toserve with such sheet. v

The sheet A andtracker-board By may be arranged for operating various automatic' nusic-prodi'icing mechanisms, but for the purposes ofthis description they will be as sumedfto be arranged for operating the pneu.

f Ina-tics for the bowing' devices, .fingering -ling tube C3.

mechanism, and' other portions, not Ishown, of an apparatus for playing avi'olin aut-os ii'iatica-lly7 in which there are four bowing devices, one .for each string of the violin.

Each bowing device is given two -apertures b1 2 inthe tracker-boardA B,- -from which ext-end tubes .C1C2 joined below lthe trackerstem of avliich eiitends'a single bowvcontrol'- The sheet' is formed withtwo series of perforations alc for each bow matching to the apertures b2 in the .tracker-'bcard.` These perforat-ions may be individually ofnioderate lengths notsuliicient toweaken the paper inaterially nor permit its distorl tion,'and aie staggered or so arranged rela'- 36o'4 board to' the .branches of a T C from the tively to each other that aperforatOIL -01' slot-a1 in one row or series willA open its Atracker-board aperture l at" the instant or a. little before the perforation ce2-of the other row or series has closed its aperture 732, thus supplying air `through the tubes C1 C2 alterlnately, or for very. brief periods through both at once, to the T C and tube' C? continuously as long a-s forati'ons continue.

By thus alternatingtheslots or perfora- -tions t-he'weakening due. to extremely long .slots is avoided. To lessen the weakening still further the series' lof perforatioiis a1 ya2' forthebows are not 'formed side byside but are separated by a rowv of perforations a a controlling' other devicesor portions of the playing mechanism, through the apertures ZJ in the tracker-board. the bowing devices may be operated for as .long periods as' may be required 'without adectingthe sheet either by weakening it or detract-ing from the `stiffness necessary to successfulfeeding.
